System installation on MacBook Pro Early 2011 A1286 

Hello. People need help and I don't know where to look anymore, he stayed
grounded my MacBook.... I bought it quite recently, it is used for work,
he came to me with a regular 500gb HDD and a high sierra system,
so I decided to make myself a bootable flash drive with macOS high
sierra I threw the drive in place of the drive went hdd 500gb and threw it
additionally SSD, the system from the pendrive was installed everything Ok spotlessly clean
 the system plays and hums. The problem started a few days ago, yeah
my SSD died, I say no problem, I bought a new one, I replaced it, I'm uploading it
pendrive I choose to boot from the pendrive, the apple i logo is shown
the bar loads endlessly. I thought maybe something about this system
happened and I looked for how to make a bootable flash drive from Windows
 MacOs system, I found it, I did it and here it is complete "sneezing" because no
it sees it as a bootable flash drive. The last resort was the internet
recovery and installation of macOS Lion but there were also stairs here
because when starting the installation it asks me to login to apple
 store, I enter my apple id password and it pops up apple id or password are
invalid and then I get an SMS with the authentication code
two-step with apple id, I can't get around it, I'm without a computer and
 I don't have anyone with a MacBook to make a flash drive with the system. Only
I hope someone on this forum can help. HELP

 Start up from macOS Recovery

To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following combinations on your keyboard. Command-R is generally recommended, especially if you never installed macOS Sierra 10.12.4 or later… How to reinstall macOS - Apple Support

Command (⌘)-R

Install the latest macOS that was installed on your Mac.


Option-⌘-R

Upgrade to the latest macOS compatible with your Mac.


Shift-Option-⌘-R

Install the macOS that came with your Mac, or the closest version still available.


2. Decide whether to erase (format) your disk

If you need to erase your disk before installing macOS, select Disk Utility from the Utilities window, then click Continue. You probably don't need to erase, unless you're selling or giving away your Mac or have an issue that requires you to erase. Learn more about when and how to erase.

3. Install macOS

After starting up from macOS Recovery, follow these steps to install macOS:

  1. Choose Reinstall macOS (or Reinstall OS X) from the Utilities window.
  2. Click Continue, then follow the onscreen instructions to choose your disk and begin installation.
  3. If the installer asks to unlock your disk, enter the password you use to log in to your Mac. If it doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk. 


  1. Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

If your Mac restarts to a setup assistant, but you're selling or giving it away, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.



If you never installed macOS Sierra 10.12.4

If macOS Sierra 10.12.4 or later was never installed on your Mac, macOS Recovery works differently:

  • Command-R is still the recommended way to start up from macOS Recovery. This combination makes sure that the installation isn't associated with your Apple ID, which is important if you're selling or giving away your Mac.
  • Option-Command-R installs the macOS that came with your Mac, or the closest version still available.
  • Shift-Option-Command-R isn't available.
